1 Be it known that we, DANIEL B. Diss andOrTo E. HAMTIL, both citizensof the United States, and residing, respectively, at

Newark, Essex county, New Jersey, and

Rahway, Union county, New Jersey, have invented certain new and usefulImprovements in Grease-Cups; and we do declare l3l16 following tobe afull, clear, and exact description ofthe invention, such as will enableothers skilled in the art to which it a appertains to make and use thesame.

This invention relates to certain new and on the cup 2. a body and thescrew threaded cap to prevent.

useful improvements in a grease cup and themethod of maklng the same,and per- .tains more particularly to an improvement shown in LettersPatent No. 1,088,770, dated March 3, 1914.

In the patent above noted, it was an aim.

to provide a frictional contact between the accidental retrogrademovement of the latter, that is, the cap could be turned manu- .1 allyin either direction but with difliculty 3 through the resistanceafforded by 'a leather disk carried by the bodyin the path of the screwthreads of the cap. i The present invention has for the primary I 1object to simplify the cup construction and disk thereon. v i

improve the method of mounting the leather i Fig. 3 1s a fragmentaryvertical section a of the cup body showing the leather disk p positionready to be clamped; and

3 Fig. 4 is aview similar to Fig. 2 in which the disk. securing lip orspur is corrugated or pressed into the leather disk.

The grease cup is of the force feed type and comprises a body 1 havingits top flange externally screw threaded, as at 2 to receive the screwthreads 3 of the cap 4 whereby on turning down the latter the lubricantwill be expressed through the discharge end 5 i of the cup body inanobvious manner.

in 8. This spur is preferably thrown up in cylindrical form tofacilitate the p0- sltioning of the leather disk 7 thereabout, afterwhich said spur is spun or curled outwardly and backwardly upon the bodyto clamp or clench the disk in place (Fig. 1).

The fibrous disk washer is of a diameter to extend in the path of andengage the ca threads 3 to afford frictional resistance su cient toeliminate retrograde turning of the cap. The periphery of the disk issmooth and, of course, the cap threads will score therein when screweddown.

- In instances where the inner periphery of the disk is circular, theclamping spur may be corrugatedor otherwise pressed into the disk, as at8, to retain the same from rotat1on.

It will thusbe noted that the body and disk securing means is a simpleand integral structure which fact renders the cup of an exceedinglypractical nature, since previous constructions embodied a plurality ofparts which were diflicult to assemble and costly in production.

.The hereindescribed method and construction equips the grease cup bodywith a disk securing means without the addition of a single part, thewhole being drawn from a single piece of sheet metal. It is thereforeobvious that the present cup' may expeditiously be manufactured with noparts to wear loose or become dislodged.

The washer is thus applied by merely slipping same over the end 5 of thecup and since the external contour of the lip conforms to that of theinternal circumference of the washer, the latter is slid over lip '6without cutting the washer. In other words the washer is applied in itsintegral form and without splitting same.

What is claimed is:

1. The hereindescribed method of securing washers intact to grease cupsand without cutting of the washers, which consists in providing abendable lip on the cup of an external form substantially correspondingto the internal circumference of the washer, then in sliding the washerover the lip and finally in bending the lip to engage beneath the washerto hold the latter in place.
